摘要:
通过岩心观察,利用普通薄片、铸体薄片以及扫描电镜分析等资料,对杭锦旗地区独贵圈闭盒1段的成岩作用及成岩相进行了划分研究。该目的层主要发育压实作用、溶蚀作用、胶结作用及少量交代作用,可识别出5种成岩相。分析各类成岩相的自然伽马、密度、中子、声波时差和电阻率等测井曲线特征,对照薄片鉴定结果进行刻画识别,可以发现在该地区声波时差和电阻率曲线对成岩相的响应较为敏感,共可划分出5种测井成岩相。声波时差228 μs/m、246 μs/m,电阻率22 Ω?m是本地区测井成岩相划分的关键判别数值。通过测井成岩相的判定,可对研究区内未取心井段进行成岩相推测及描述。
Abstract:
Through core observation,common thin slices,cast thin slices and scanning electron microscopy (SEM) data,it was classified and studied the diagenesis and diagenetic facies of the 1st member of the Dugui trap in the Hangjinqi area. The target layer mainly develops compaction,dissolution,cementation,and a small amount of metasomatism,and 5 kinds of diagenetic facies can be identified.By analyzing the logging curve characteristics of various diagenetic facies such as natural gamma,density,neutron,sonic time difference,and resistivity,characterizing and identifying the thin section identification results,it can be found that the sonic time difference and resistivity curve are more sensitive to the response of diagenetic facies in this area.A total of 5 logging diagenetic facies can be divided.The interval transit time of 228 μs/m and 246 μs/m,and the resistivity of 22 Ω?m are the key distinguishing value for the division of logging diagenetic facies in this area. Through the determination of logging diagenetic facies,diagenetic facies can be inferred and described in the uncorked well section in the study area.
